dc.description.abstract | Objective: Polycystic ovary syndrome (PCOS) is associated with altered lipid profile and increased small, dense LDL particles (sdLDL). Considering that paraoxonase 1 (PON1) is an anti-oxidative enzyme located on high-density lipoprotein (HDL) particles, the aim of this study was to investigate the connection between oxidative stress (OS) and PON1 activity with lipoprotein subclasses in PCOS depending on obesity. Methods: In 115 PCOS patients lipoprotein subclasses distributions were determined by gradient gel electrophoresis. OS status was assessed by total oxidative status (TOS), advanced oxidation protein products (AOPP), malondialdehyde (MDA), prooxidant-Antioxidant balance (PAB), total antioxidant status (TAS) and superoxide dismutase (SOD) and PON1 activity. Results: Overweight/obese PCOS patients (n=55) had increased OS compared to normal weight patients (n=60). In addition, overweight/obese group had lower HDL size and higher proportion of HDL 3a subclasses (P<0.05). PAB was in negative correlation with HDL 2a (P<0.001), whereas MDA and SOD correlated positively with HDL 3 subclasses (P<0.05). Serum PON1 activity was positively associated with proportions of PON1 activity on HDL 2b (P<0.05) and 2a (P<0.01), but negatively with the proportion on HDL 3 particles (P<0.01). LDL B phenotype patients had increased TAS, SOD and PON1 activity on HDL 2b, but decreased PON1 activity on HDL 3 subclasses. Conclusion: OS is associated with altered lipoprotein subclasses distribution in PCOS patients. Obesity in PCOS affects the profile of HDL subclasses, reflected through the reduced proportion of PON1 activity on HDL 3 subclasses in the presence of sdLDL particles. | |
